BUTTONHOLE-GAGE.

, Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed-November 3, 1917. Serial No. 200,103.

To all whom it may concern:

Be it known that I, MAUD E. WALTER, a citizen of the United States, residing at Hayward, in the county of Sawyer and State of Wisconsin, have invented new and useful Improvements in Buttonhole- Gages, of which the following is a specification.

This invention is a button hole gage more particularly adapted for use in connection with machines and their attachments employed for button hole work.

One object of the invention is to provide a gage that is simple in construction, one that may be readily adjusted for the desired spacing of the hole, one that may be readily attached and detached from the machine, and one that will clearly perform its function.

Another object is to provide a gage consisting of few parts, made of suitable material that will not readily wear out, and one that will be cheap to manufacture.

Broadly stated, the invention relates to a U-shaped clamp formed of resilient material and having twoprojecting lugs, a graduated gage adapted to be posit'oned be' tween the lugs, said gage being provided with an angular arm and end, and a set screw cooperatively connected with one of the lugs to hold the gage in a predetermined position, said U-shaped clamp being so formed that it will permit of being readily attached to and detached from a button hole machine.

One practical form of construction and assembly will be described and illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the gage attached to a machine;

Fig. 2 is a perspective view of the clamp and measuring bar; and

Fig. 3 is a side elevation of the clamp and set screw.

In the preferred embodiment shown in the drawing, the U-shaped clamp is provided with the projecting legs indicated at 5 and 6 that are joined together by a connecting piece indicated at 7 The legs 5 and 6 are preferably formed of resilient material and are somewhat curved in their outline, so that they may readily engage with the sides of a button hole attachment indicated at A.

Disposed upon the connecting pieces 7, are two lugs indicated at 8 and 9. These lugs are spaced apart and project at right angles to the connecting pieces 7 The lug 8 is provided with a threaded hole which is adapted to receive a suitably threaded set screw indicated at 10. To ride within the slot formed by the spacing of the lugs 8 and 9 apart, is

- a gage comprising the body portion indicated at 11 having suitable markings or graduations thereon indicated at 12.

At one end of the gage 11, there projects an arm 13.- This arm 13 projects at right angles to the body portion 11. The arm 13 is provided with an angular end, indicated at 14, the angle formed between the arm 13 and the end 14 being substantially 90.

The gage 11 is preferably made of thin, flat stock, and the material of which it is composed may be any that is suitable for the purpose. As shown the graduations are inches and the subdivisions are of 8ths. These markings are purely arbitrary and any system may be employed.

In practical operation,the U-shaped clamp by means of its resilient legs 5 and 6 is removably positioned upon the button hole attachment A adjacent the presser bar 15 so that the gage 11 and its arm 13 project to the right. The gage may be moved within the slot formed between the lugs 8 and 9 by loosening the set screw 10, and the graduations formed on the gage will permit the operator to determine the exact width of goods lying between two of the button holes.

When in their operative position, the legs 5 and 6 will firmly hold the clamp in position on account of the resiliency of the material in those members. After one button hole has been worked, the goods is drawn to the right and the arm 13 and its end 14 are placed in position over the first or worked button hole, at which time the second button hole will be in its proper place to be operated upon by the needle of the machine. The succeeding button holes may be worked in a manner similar to that of the first and second as the gage will correctly space the holes a proper distance apart.

Minor changes in the form, proportions, and details of construction may be resorted to without departing from the spirit of the invention or the scope of the appended claim.

What is claimed as new is The combination with a button hole attachment for machines, of a U-shaped clamp thereon, said gage being; adapted tQ;.1ie"'be? 5 tween the lugs and be securely held in adjusted position by the set screw actinggtheres on, the gage having an angular end adapted In testimony Whereef I aflixmy signature.
